The present invention relates to loose leaf binders and moreparticularly to the type in which the binder comprises two bindingmembers, one of which has impaiing projections thereon and the other ofwhich has locls the purpose of repair or the substitution of others.Another object of the invention is to provide a leaf-retaining bar whichmay cooperate with a transfer member having inipaling projections andassociated with a loose leaf binder so that the transfer member may beused as a temporary binder as well as for transferring leaves in thebinder.

To these and other ends, the invention consists of certain parts andcombinations of parts all of which will be hereinafter described: thenovel features being pointed out in the appended claim.

In the drawings Fig. 1 is a perspective view of the loose leaf bindershowing the binder members separated;

Fig. 8 is'a plan view of the retai and V Fig. 9 is a fra mentary sideview with the parts in section showing the transfer memher with theretaining bar arranged thereon.

In the illustrated embodiment of this invention 1 indicates the backpiece, 2 the cover leaves and 8 supporting bars for the binding members,the supporting bars being hinged at l to the hack piece 1 and hinged at5 to the cover members 2.

Prior to this invention, it has been customary, in this ty lie ofbinder, to mount the bars of the binding members in the positionsoccupied by the supporting bars 3. The result is that when the binderbecomes broken, in

either of its binding members, the binder must be thrown away or anexpensive repair bill is involved. According to this invention thebinding members may be readily repaired or replaced by others, due tothe fact that the binding members are detachably arranged on the innerfaces of the supporting bars 8. To this end, the binding membe 6 whichis in the form of a bar or strip with spaced impaling projections 7extending laterally from one side thereof is, by screws 8 passed throughthe bar 6, anchored to a supporting bar 8 and held to'such supportingbar. The other binding member or bar 9 is in the form of a chan nelmember, the open s1de of which lies on "the inner side of the bar 3 andis held thereto by screws 10. This binding member 8 has the lockingmeansarranged therein in the form of a usual sliding locking bar 11 having afin er niece atone end through which it 1s t) I V I o k: A 0

moved in one d1 ection against the action of a helical spring 12 alsocontained within the binding member 9. This locking bar has shouldersthereon as usual for engagement with shoulders 13. formed on some of theimhousing 9 to be engaged by the locking bar 11.

lVith this arrangement either or both of the binding members may bereadilyv disconnected from the supporting bars 3 for the purpose ofrepair or for replacement by others.

As it is customary in this type of binder, there may be employed atransfer member comprising, in this instance, a. bar 15 with ims palingposts or projections 16 extending therefrom, these impaling posts beingadapted to pass into any one of the openings 17 in the leaves 18 betweenthe openings through which the impaling projections 7 pass. Thistransfer member also has projecting from the opposite side of the barshort posts 19 with shoulders 20 thereon. These short posts are adaptedto pass through the openings 21 in the housing 9 to be engaged bylocking shoulders on the locking bar 11, as is well-known in this art.Openings 1% are provided in the transfer member 15 which aline with theopenings let so that the shouldered posts 7 may pass through to engage t1e clutching means.

Another feature of this invention is to associate with the transfermember of a binder of this type, means for retaining the leaves on thetransfer member so that the transfe member may act as a temporarybinder. This means, in this instance, consists of a retaining bar 22having openings 23 through which the posts 16 of the transier Adjacentthe ends of the retaining bar are spring clutches 2% each in the form ofa leaf spring riveted at one end at 25 to the retaining bar 22 andhaving its free end 26 extending slightly over one of the openings 23 sothat when post 16 is passed through the opening, the spring clutch willbe displaced and will enter into clutching engagement with a portion ofthe post projecting Ul rough the opening. A lip 27 projects from oneside of the clutch beyond a side of the retaining bar and may bemanipulated to break the engagement between the clutch and the post inorder to permit the withdrawal of the retaining bar from the transfermember. l Jith this arrangement the transfer member with the retainingbar may be used as a temporary binding means for those leaves which havebeen removed from the binding projections Y. l he retaining member 22may be arranged in apocket 28 formed on the inner face of one of thecovers 2.

From the foregoing it will be seen that there has beenprovided, in aloose leaf binder of the type having the binding member provided withimpaling projections and the binding member having locking means forinterlocking with impaling projections on the first-mentioned member,means for securing the binding members to the cover so that the membersmay be readily removed or re placed by others. There has also beenprovided in connection with a transfer member in binder of the classdescribed, a retaining iner ber may pass.

the impaling projections on the first-named binding member, and atransfer member hav- WILLIAM F. W ARNER, J R.
